How to use the manage_add - methods
by Espen Sorbye Frederiksen 16 Nov '00

16 Nov '00

I am a very novice zope/python user that needs to become an expert as soon as possible, since my whole dissertaion is based on Zope/Python. I have read all documentation availible on the zope.org site but can't find the answer to the following... 1. To run python scripts written as dtml methods. Do I simply use dtml-call from another dtml document/method? 2. To create folders, mthods etc in the code. I have found some functions manage_addDTMLMethod, manage_addFolder, but how do I use them? 3. I need to make a site that allows users to register ( i.e. to generate user folder with some standard documents in them). Anyone have hints regarding this? (or in fact a whole application I can use?) I appreciate any kind of contribution, Espen

Invalid Date-Time String - Yihaw
by konteXXt＠t-online.de 16 Nov '00

16 Nov '00

Hello again, I use Yihaw and have a problem with the yihawNewsItem and IE (4.0): When I add a longer news, I got the error: Invalid Date-Time String with IE, not with netscape. The only way: I take a part of the massage and add the rest by editing. What's wrong ? Thank you for help Mechtild -- in der Heimat tut sich was: http://www.wolterdingen.de konteXXt - Web-Konzept-Text-Design 07705 / 919391

Letting a user create something
by Anders Eriksson 16 Nov '00

16 Nov '00

Hello, I have installed the Yihaw product and it work just fine. But I have one problem, and I guess this is kind of a general question. How do I let the user do something? e.g. Create a folder. In this particular case it's a Yihaw folder (or any of the other Yihaw entities. I understand that the user must have the rights to do it (which I have done) but somehow there must be some method/function/special character that I can include in my dtml 'code' The standard dropdown box is just fine but I want to have it in my own page that has my coloring scheme, etc ... I guess that this is a stupid question but PLEASE PLEASE answer this question so I can continue my adventure into the world of Zope! -- Best regards, Anders mailto:ame@swipnet.se To me, boxing is like couples having sex, except there's no foreplay, no naked people and the people are hitting each other with big red gloves.

DoD Users That You Know Of?
by Kraska, Andy W. 16 Nov '00

16 Nov '00

I am considering application of Zope to a Department of Defense (DoD) customer. It would be very helpful to talk with other DoD type users of Zope so we can establish to other DoD people that the product's already successfully in use. Can you give me contact information on any such users please? v.r ......Andy K. (719) 637-7324 and awkraska(a)tasc.com

dtml-if and dtml-with problems
by James Sintz 16 Nov '00

16 Nov '00

Could someone tell me why the follow statement is never true. <dtml-in "news.objectValues(['newsLetters'])" sort="nl_goLiveDate"> <dtml-if "nl_goLiveDate == '2000/11/16'"> <h2><dtml-var nl_subject> - <dtml-var nl_goLiveDate></h2> <p> <dtml-var nl_body fmt=structured-text> </p> </dtml-if> </dtml-in> The news folder contains several newsletters and one of them DOES have a 'nl_goLiveDate' of 2000/11/16 yet the above express seems to be always false. What obvious mistake am I making? Ideally I would like the page to show only the newsletter that has the same date as today's date. Jamey

RE: [zope] Help!!! (was: sudden ZClass breakage)
by James Sintz 16 Nov '00

16 Nov '00

My ZClass is broken, but only in Zope 2.2.2 why? I exported my ZClass and imported it into a Zope 2.2.0 installation and it works GREAT. I figured, some how, I must have really screwed up my 2.2.2 installation so I removed it off my server. I then downloaded and installed 2.2.2 again, installed all the products that I use (same products on the 2.2.0 server) and then imported my ZClass. I tried to add an instance and it errors out with "Invalid Date-Time String" again. What is up??? Could some Zope power user fill me in? Why would the same ZClass work fine in 2.2.0 and not work in 2.2.2? HELP!!!!!!! Thanks!

Avoiding acquisition aka testing for contained objects
by Stefan H. Holek 16 Nov '00

16 Nov '00

If I want to know whether a certain object is contained in the current folder I do this: <dtml-if "'index_html' in this().objectIds()"> yes it's here <dtml-else> not here </dtml-if> Id like to know whether this is the best/most efficient way to do it. Things like hasattr() are subject to aquisition i.e. they would find an index_html method along the acquisition path; something I do not want. I also cannot bracket everything in a <dtml-with ... only> because chopping my namespace is not what I want either. TIA, Stefan -- Things work better when plugged in

Passing paramaters for form processing
by steve smith 16 Nov '00

16 Nov '00

How do I set some parameters for use in a form processing method? I have a HTML "FORM" tag referencing a DTML method name, and I want that method to have visibilty of some variables from the calling methods space. I've tried passing them with the url (eg, "ACTION=/someurl?fred=<dtml-var blah>") and by using REQUEST.set syntax in the calling method. Neither seems to result in the variable being visible to the form processing method. Any ideas? Steve
